Pushing 800W of Wireless Power at 5 Meters

Posted by timothy on from the distance-rocks dept.

Joe Decker writes "The Nevada Lightning Laboratory has experimented with Nicola Tesla's methods of wireless power transmission to push 800 Watts over 5 meters, besting MITs mark of 60W over 2 meters last year. (May I dream of wireless laptop power? I hate power cords.)"

    I share those same thoughts.

    If a milliwatt cellphone has the (potential) ability to cause DNA recombination errors & thereby mutant cells, what on earth would an 800 watt power wave do to you?!?!? Pass. It's bad enough my electric hybrid Honda bathes me with EM waves ever time I accelerate... I don't need my laptop doing it too.

    The problem with cell phones isn't really the amount of EM radiation, it's the fact that it is ionizing radiation.
    It's the same reason only UV rays give you sunburns/skin cancer, they are the only ionizing radiation.

    I don't know what frequency they are using (I didn't read the article, of course), but if they use a frequency of non-ionizing radiation, there isn't much of a problem.
    (That isn't to say there is no problem, but the effects of non-ionizing radiation are significantly less. That's why radio or TV towers don't just sterilize everyone in a mile radius)
